Hydrocephalus

Hydrocephalus is caused by too much cerebrospinal fluid in the brain.^[1] Which can be mistaken for brain cancer, brain dysfunction or aneurysms. This causes higher pressure inside the skull. Older people with this may have headaches, double vision, poor balance, urinary problems, personality changes, or mental impairment. In babies, it may be seen as a rapid increase in head size.

Hydrocephalus can happen as a birth defects or can also happen later in life.^[2] Other causes include meningitis, brain tumors, traumatic brain injury, or brain hemorrhage.
